Terms and conditions

Last updated: 31 October 2026

These terms apply to every order of the administrative tax-return preparation service offered on this website.

Provider

Digital & Tech Consulting - Ruben António de Jesus Marques. The service is provided by a sole proprietorship established in Luxembourg. Company details are in the legal notice. Contact: through the the contact form.

The service

The service is the administrative preparation of your Luxembourg personal income tax return for the tax year agreed with you, based on the documents and information you provide. It is administrative preparation, not fiscal advisory services: it includes no tax advice, no tax planning and no representation before the tax authority beyond the submission described below.

Standard package: I prepare the return and you submit it yourself. Premium package: I also submit it for you, under a mandate you grant me in MyGuichet.lu. Custom package: the scope and price are set out in a written quote, which you must accept before work starts. The tax assessment is decided by the tax authority; no refund or result is guaranteed.

How the contract is made

You send a request through the contact form. I answer with a written offer stating the package, the price and the documents needed. For a custom package, the written quote must be accepted before work starts. The contract is made when you accept the offer in writing; an e-mail is enough. A request through the form is not an order.

The contract is made in the language of the offer: French, English, German, Portuguese or Luxembourgish.

Prices

Prices are those shown in the Prices section of this website on the day of the offer, in euros, VAT included; the offer states the final price. The custom package is priced in a written quote accepted before work starts. A couple taxed jointly pays one package price. Documents beyond a package’s allowance cost the extra-document price shown there, and I tell you before any extra cost arises.

Payment

Payment by bank transfer on invoice, after you approve the draft and before the return is submitted or handed over. You receive an invoice for every payment.

Your part

You provide complete and accurate documents and information in good time and tell me about any change. The return is prepared from what you provide. You check the draft and approve it before it is submitted; the return remains yours, and you are the taxpayer before the tax authority.

Right of withdrawal

If you are a consumer, you may withdraw from this contract within 14 days without giving any reason (Consumer Code, articles L. 222-9 and following). The period ends 14 days after the day the contract is made.

To withdraw, tell me of your decision by a clear statement, for example an e-mail or a message through the contact form, before the period ends. You may use the model form below; it is not required.

If you withdraw, I refund every payment received from you without undue delay and at the latest 14 days after I receive your statement, by the means of payment you used, at no cost to you.

If you asked me to start work during the withdrawal period, you pay an amount in proportion to the work done until you told me of your withdrawal. If you asked me expressly to start before the period ends and acknowledged that you lose your right of withdrawal once the service is fully performed, the right ends when it is. I ask for this request and acknowledgement in writing before I start.

Model withdrawal form

(Complete and return this form only if you wish to withdraw from the contract.)

  • To withdraw, send your statement through the the contact form.
  • I hereby give notice that I withdraw from my contract for the following service:
  • Ordered on:
  • Name of the consumer:

Liability

I prepare your return with care and according to the law in force when it is prepared, and I correct a mistake of mine free of charge. I am not liable for the consequences of missing, late or wrong information or documents, for the decisions of the tax authority, or for the amount of tax or refund it sets.

Except for intent or gross negligence, my liability is limited to the price paid for the service concerned. Nothing in these terms limits the rights mandatory law gives you as a consumer.

Confidentiality and personal data

Your documents and information are kept confidential and used only to provide the service. How personal data is handled is described in the privacy notice.

Complaints and mediation

Send any complaint through the the contact form. If we cannot agree, you may turn free of charge to the Luxembourg consumer mediator, the Service national du Médiateur de la consommation (mediateurconsommation.lu).

Applicable law and courts

These terms and the contract are governed by Luxembourg law, and the courts of Luxembourg have jurisdiction. As a consumer, you keep the protection of the mandatory rules of your country of residence and may also go to the courts there where the law allows it.

The version of these terms in force on the day you accept the offer applies to your contract.
